  • progressive loss of renal function as defined by glomerular filtration rate (GFR) ≤ 45 mL/min/1.73 m²;
  • be clinically stable in the opinion of the investigator;
  • be serum negative for HBsAg, anti-HBsAg, antibody to hepatitis B core antigen (HBcAg), Hepatitis C virus (HCV), and human immunodeficiency virus (HIV);
  • if a woman of childbearing potential, agree to consistently use a highly effective method of birth control from screening visit through the treatment phase and for up to 28 days after the last injection;
  • is not scheduled to undergo a kidney transplant in the next 12 months;
  • be able and willing to provide informed consent.
Exclusion Criteria
  • if female, is pregnant, breastfeeding, or planning a pregnancy;
  • has a history of or is considered by the investigator to be at high risk for recent exposure to HBV, HCV, or HIV; for example, current intravenous drug use, has unprotected sex with known HBV/HIV positive partner;
  • has known history of autoimmune disease;
  • has previously received any HBV vaccine;
  • has a history of sensitivity to any component of study vaccines;
  • has current illness other than renal disease or has substance or alcohol abuse that in the opinion of the investigator would interfere with compliance or with interpretation of the study results;

  • is unwilling or unable to comply with all the requirements of the protocol;
  • has received any blood products or immunoglobulin within 3 months prior to study entry, or likely to require infusion of blood products during the study period;
  • has received the following prior to the first injection:
  • 3 days: erythropoietin (exclusionary window does not apply for subjects on dialysis)
  • 7 days: intravenous iron
  • 21 days: any inactivated virus vaccine
  • 28 days:
  • any live virus vaccine
  • systemic corticosteroids (more than 3 consecutive days) or other immunomodulators or immune suppressive medication, with the exception of inhaled steroids
  • granulocyte or granulocyte-macrophage colony-simulating factor (G/GM-CSF), any other investigational medicinal agent
  • At any time: an injection of deoxyribonucleic acid plasmids or oligonucleotide

Primary Outcome Measures
NameTimeMethod
Seroprotection Rate (SPR) = Percentage of Participants Who Have a Seroprotective Immune ResponseWeek 28

SPR is the percentage of participants who have a seroprotective immune response (antibody level to anti-HBsAg greater than or equal to 10 milli-international unit \[mIU\]/mL) after HEPLISAV-B compared to that after Engerix-B.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Anti-HBsAg Greater Than or Equal to 100 mIU/mL at Weeks 4, 8, 12, 18, 24, 28, 36, 44, and 52Weeks 4, 8, 12, 18, 24, 28, 36, 44, and 52
SPR of Participants With Type 2 Diabetes Mellitus at Week 28Week 28

SPR is the percentage of participants who have a seroprotective immune response (antibody level to anti-HBsAg greater than or equal to 10 milli-international unit \[mIU\]/mL) after HEPLISAV-B compared to that after Engerix-B.

Reactogenicity as Measured by the Percentage of Participants With Local and Systemic Post-injection Reactions Within 7 Days After Each Injection Visit7 days after each injection visit (Weeks 0, 4, 8, and 24)

Local reactions include redness greater than or equal to 25 mm, swelling greater than or equal to 25 mm, and pain.

Systemic reactions include malaise, headache, myalgia, fatigue, and fever (temperature greater than or equal to 38ºC).

This table presents post-injection reactions at active injection visits only. Post-injection reactions after the third (placebo) injection visit in the HEPLISAV-B group are not included.

Seroprotection Rate (SPR) = Percentage of Participants Who Have a Seroprotective Immune Response at Weeks 4, 8, 12, 18, 24, 28, 36, 44, and 52Weeks 4, 8, 12, 18, 24, 28, 36, 44, and 52

SPR is the percentage of participants who have a seroprotective immune response (antibody level to anti-HBsAg greater than or equal to 10 milli-international unit \[mIU\]/mL) after HEPLISAV-B compared to that after Engerix-B.

Serum Anti-HBsAg Geometric Mean Concentration (GMC) at Weeks 4, 8, 12, 18, 24, 28, 36, 44, and 52Weeks 4, 8, 12, 18, 24, 28, 36, 44, and 52
